    I assume you meant "info", not "status". If so, that doesn't look all
    that interesting:

    [torvalds@i5 linux]$ cat /sys/kernel/debug/dri/0/i915_drpc_info
    HD boost: no
    Boost freq: 0
    HW control enabled: no
    SW control enabled: no
    Gated voltage change: no
    Starting frequency: P0
    Max P-state: P0
    Min P-state: P0
    RS1 VID: 0
    RS2 VID: 38
    Render standby enabled: yes
    [torvalds@i5 linux]$ cat /sys/kernel/debug/dri/0/i915_cur_delayinfo
    Requested P-state: 0
    Requested VID: 0
    Current VID: 37
    Current P-state: 0

    (This is in the "working state" - I rebooted because I can't stand
    working with a machine that feels like a 110baud terminal).

    I don't have this commit at all, it wasn't part of the merged series.
